ABSTRACT:
A flexible implantable luminal device is disclosed, which is made from a porous cylindrical tube manufactured from extruded fluoropolymer. A fluoropolymer filament is wrapped helically around the external surface of the tube. The filament is fused to the tube to form a unitary composite structure by heating the wrapped tube to a temperature above the melting points of the fluoropolymers. The resulting composite is a radially reinforced flexible luminal prosthesis suitable for implantation, particularly, as a vascular graft or endoprosthesis. Also disclosed is a method for manufacturing the prosthesis.
